So the IDF did not surround Sabra and Shatilla with tanks?

As to the decision for the entry of the Lebanese militiamen into the Sabra and Chatila camps, it appears from the testimony of Rafael Eitan, Israel's Chief of Staff, before the Israeli Commission of Inquiry that it was taken by him and by Sharon on September 14, 1982. This was followed by meetings between those two military chiefs and the Phalangist commanders to coordinate the operation of the militiamen's entry into the camps. The decision to allow the militiamen's entry into the camps was approved by the Israeli Cabinet on September 16 after it began to be put into execution.
Yes, after WW-II the Germans population denied any knowledge of concentration/extermination camps.

The Commission determined that the massacre at Sabra and Shatilla was carried out by a Phalangist unit, acting on its own but its entry was known to Israel. No Israeli was directly responsible for the events which occurred in the camps. But the Commission asserted that Israel had indirect responsibility for the massacre since the I.D.F. held the area, Mr. Begin was found responsible for not exercising greater involvement and awareness in the matter of introducing the Phalangists into the camps. Mr. Sharon was found responsible for ignoring the danger of bloodshed and revenge when he approved the entry of the Phalangists into the camps as well as not taking appropriate measures to prevent bloodshed. Mr. Shamir erred by not taking action after being alerted by communications Minister Zippori. Chief of Staff Eitan did not give the appropriate orders to prevent the massacre. The Commission recommended that the Defense Minister resign, that the Director of Military Intelligence not continue in his post and other senior officers be removed.
Your statement absolving Israel is morally bankrupt.
